Does an OPK shows a positive LH surge even during ovulation? If not, how much time before ovulation LH drops.
LH AND fertility: Clearblue offers a range of ovulation test and fertility products, all of which monitor luteinizing hormone (LH) in urine to identify the time of peak fertility. The Clearblue Fertility Monitor and Clearblue Advanced Digital Ovulation Test also measure another key hormone, estrogen (estrone-3-glucuronide) to identify the period of high fertility that occurs prior to the LH surge. Monitoring these two hormones helps women identify the fertile days of their cycle enabling them to time intercourse to the days when conception is most likely There are only a few days per cycle when a woman is fertile and can conceive. Evidence shows that this time of high fertility usually spans 6 days, starting approximately 5 days prior to ovulation and ending on the day of ovulation itself.1 The 6-day fertile period is affected by: The lifespan of the egg, which is up to 24 hours after ovulation The lifespan of sperm which is more variable. The median is 1.5 days, but sperm can survive up to 5 days in the sperm supportive mucus found in the fertile days of the cycle. Sperm survival is therefore dependent on the type and quantity of the mucus within the cervix, and the quality of the sperm itself. The two most fertile days of this 6-day window are known as peak fertility days. These peak fertile days are the day prior to ovulation and the day that ovulation takes place.2 Studies show that a surge in LH levels occurs 24-36 hours prior to ovulation,2 and that this LH surge is an accurate and reliable marker of impending ovulation.3-7 The urinary LH surge pinpoints the two peak fertile days of a woman's cycle, with intercourse on these days being shown to be associated with the highest likelihood of conception. ...Read more
